Studies of paste microstructure with instruments such as the scanning electron microscope are an essential component of many of our investigations.
Petrographic examination of structures affected by durability mechanisms such as alkali-silica reaction is a core pursuit at DRP.
Scanning electron microscopy with energy-dispersive x-ray spectrometry allow us to obtain in situ determinations of the chemical composition of materials, such as this pool finish.
Understanding the nature and composition of raw materials, such as this fly ash particle, is a fundamental aspect of our work.
Sometimes it is important to know when there isn’t a problem. Here is an example of some happy concrete.
Combining field work and petrography allows us to unravel complex deterioration histories, such as when both freeze-thaw damage and alkali-silica reaction are linked to joint spalling.
